Description
Technical field
A kind of activation charging gear of the utility model belongs to activation charging gear technical field.
Background technology
The feeder load mainly relies on and regulates the variable wheels change of vapour-pressure type disturbance force at present.Pneumatic regulation technology is the technology seventies in last century, by the all-electronin technology elimination.Feeder is the non-real subresonance technology of fixed rotating speed at present.Because body is unloaded, fully loaded during with variable load, the resonance speed drift is a variable, when adopting constant rotational speed, can not guarantee that body works in desirable subresonance district, lowers the life-span of equipment.Under permanent rotating speed, utilize the side-play amount size of pneumatic structure adjusting pouring weight, disturbance force is regulated inaccurate, and DeGrain also need add the pneumatic accent force mechanisms of a cover constant speed in addition, and cost is high, and maintenance is inconvenient, no fender system.
200720034199.5 number utility model patent is carried a kind of activation charging gear of arch.Comprise hopper, vibrating motor, damper spring; In hopper, be provided with stock guide; High feed box upper surface, stock guide top and being deep in the bin outlet; The inclination alpha that forms between line between stock guide edge and the hopper bottom discharge mouth edge and the horizontal surface equals or is slightly less than the angle of repose of material, hopper bottom discharge mouth adjustable size.Bilateral symmetry at hopper is installed two vibrating motors, and vibrating motor is vertically arranged, does backward rotation, straight-line oscillation in the horizontal direction, the function of realization activation feed bin bottom material and blanking.Relative position between flitch and the discharging opening according to the different appropriate design of the angle of repose of heterogeneity material, guarantees normal blanking when work, material self-locking during shutdown.Whole hopper is by four spring-loadeds.Advantage is that whole feeder is simple in structure, and running is reliable.
The shortcoming of this device is: this equipment is fixed rotating speed, does not adopt the subresonance technology to come the activation material, accurately quantitative discharging; Because body is unloaded; Fully loaded during with variable load, the resonance speed drift is a variable, can not guarantee that body works in desirable subresonance district.This equipment noise is high, and vibration can drive miscellaneous equipment greatly also along with vibration, brings the related damages effect can for other equipment.The not enough undercapacity of this equipment disturbance force, discharging is regulated inaccurate, DeGrain, cost is high, safeguards inconvenience, no fender system.
The utility model content
The utility model overcomes the deficiency that prior art exists, and technical matters to be solved is to carry a kind of activation charging gear that guarantees that material is unobstructed, installation is simple and convenient, the discharging accuracy rate high, variable range is big of arch.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of activation charging gear; Comprise the activation main body, pass the spring that shakes, pass shake frame, exciting source, bracing frame and support spring, the activation main body is installed in a plurality of bracing frames top through support spring, and curved stock guide is installed the activation body interior and the stock guide bottom is provided with feed opening; One side of activation main body is equipped with and passes the frame that shakes through the biography spring that shakes; Biography is shaken and through substrate exciting source is installed on the frame, and the stock guide top is equipped with the wedge top, and the angle between wedge top and the said stock guide is less than the material angle of repose.
Said activation main body top is former feed bin outlet, and former feed bin outlet is flexible coupling through first and the activation main body flexibly connects; Described a plurality of bracing frame is installed in the band conveyor both sides side by side, said feed opening be positioned at band conveyor directly over and be flexible coupling through second with band conveyor inlet and flexibly connect.
Described exciting source is a vibrating motor.
The following beneficial effect that the utility model compared with prior art has.
1, the utility model adopts servo-actuated subresonance technology and variable frequency control; Exciting source can be according to frequency of operation in the physical property identification subresonance scope of solid granule, and automatic tracking body resonance frequency is regulated as required; Guarantee the unobstructed of material, and reached accurate feeding.
2, the utility model activation main body is installed on the bracing frame through support spring, when the activation body vibration, plays buffer action, and other equipment can not cause damage along with vibration, prolonged the service life of entire equipment.
3, the angle between the utility model wedge top and the stock guide is less than the material angle of repose, and when exciting source was out of service, angle of repose was carried out self-locking, stops feed, need not gate, does not have to leak and spills phenomenon.
4, the utility model feed opening be positioned at band conveyor directly over, blanking centering has effectively been played anti-deviation effect.
5, the utility model feed power demand is less, can 24 hours of continuous run, improved work efficiency.
6, the utility model and up and down bonded assembly equipment adopt the hermetically sealed design that is flexible coupling, no any spilling Lou and the flour dust overflow phenomenon improved working environment.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model.
Among the figure, 1 is the activation main body, and 2 for passing the spring that shakes, and 3 for passing the frame that shakes, and 4 is exciting source; 5 is bracing frame, and 6 is support spring, and 7 is band conveyor, and 8 is stock guide, and 9 is feed opening; 10 is the outlet of former feed bin, and 11 is first to be flexible coupling, and 12 for wedge pushes up, and 13 is second to be flexible coupling.
The specific embodiment
As shown in Figure 1; A kind of activation charging gear of the utility model; Comprise activation main body 1, pass the spring 2 that shakes, pass shake frame 3, exciting source 4, bracing frame 5 and support spring 6, activation main body 1 is installed in a plurality of bracing frames 5 tops through support spring 6, and curved stock guide 8 is installed in activation main body 1 inside and stock guide 8 bottoms are provided with feed opening 9; One side of activation main body 1 is equipped with and passes the frame 3 that shakes through the biography spring 2 that shakes; Biography is shaken and through substrate exciting source 4 is installed on the frame 3, and stock guide 8 tops are equipped with wedge top 12, and the angle between wedge top 12 and the said stock guide 8 is less than the material angle of repose.
Said activation main body 1 top is former feed bin outlet 10, and former feed bin outlet 10 is flexible coupling through first and 11 flexibly connects with activation main body 1; Described a plurality of bracing frame 5 is installed in band conveyor 7 both sides side by side, said feed opening 9 be positioned at band conveyor 7 directly over and be flexible coupling through second with band conveyor 7 inlet and 13 flexibly connect.
